Gyarah Sidi are the remains of Mughal Emperor, Humayun’s astrological observatory, situated at a stone’s throw from Babur’s Mehtab Bagh, in a field on the banks of the Yamuna river in Agra. Gyarah Sidi or Eleven Steps refers to the steps overlooking the hemispherical cavities in the ground from which astronomical readings could be taken. Though nowhere close to their size, Humayun’s observatory is an interesting, diminutive precursor to the massive Jantar Mantars at Jaipur and Delhi built nearly 200 years later.
